WARREN A. PATTERSON, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE COTTON HAR-VESTER COMPANY, OF ST. LOUIS, MISSOURI, A CORPORATION OF SOUTH DAKOTA.

COTTON-SEPARATOR.

To all whom "it may concern.

Be it known that I, WARREN A. PATTER- SON, a citizen of the UnitedStates, and resident of St. Louis, Missouri, have invented certain newand useful Improvements in Cotton-Separators, of which the following isa specification containing a full, clear, and exact description,reference being had to the accompanying drawings, forming a part hereof.

My invention relates to improvements in cotton separators, the object ofmy invention being to generally improve the construction of the machineshown and described in my application for Letters-Patent filed August22, 1908, serially numbered 449,863.

For the above purposes my invention con sists in certain novel featuresof construction and arrangement of parts as will be hereinafter morefully described, pointed out in my claims and illustrated in theaccompanying drawings, in which:

Figure 1 is an elevation of the complete apparatus; Fig. 2 is a plan ofthe complete apparatus; Fig. 3 is an enlarged detail elevation, partlyin section, illustrating the construction of the. cylinder employed inmy machine; Fig. 4 is a front end elevation of the machine showing themeans for adjusting the incline of the machine frame and partscarried'thereby; Fig. 5 is an enlarged detail sectional elevationillustrating the means whereby the saws and the brush are rotated; and,Fig. 6 is an enlarged detail sectional elevation showing the relativepositions of the cylinder, the saws and the brush.

Referring by numerals to the accompanying drawings: 1 designates theframe of the machine. 2 designates a hinge member carried by the lowerend of the frame. 3 designates the shaft inserted through the hingemembers 2. 4 designates bearings for the shaft 3 and 5 designatesstandards for the bearings 4. At the opposite end of the machine frameand located on the cross tie of the machine frame 1, I position a plate6 which is engaged by the end of the jack 7, which jack is supported inthe internally threaded socket 8 supported in the cross tie 9, whichcross tie is supported by the standards 10.

To prevent lateral movement of the frame 1, I have provided guides 11which are se- Specification of Letters Patent.

Application filed. August 27, 1909.

Serial No. 514,853.

cured to the frame 1, each of which engages the standards 10.

Cross ties 12 are supported upon the upper faces of the frame 1 andbearings 13 are positioned thereon, and, to provide for an adjustment ofthe separator relative to the saw blades, I have provided wedge-shapedblocks 14 which are positioned between the bearings and the cross ties.

Rotatably mounted in the bearings 13 .is a shaft 15 and carried by thelower end of the shaft 15 is a pulley 16, and, embracing said pulley isa belt 17. Carried by the frame 1 and secured to its under side arecross ties 18. Carried by each cross tie 18 is a bearing 19 androtatably mounted in the bearings 19 is a shaft 20. Embracing the shaft20, immediately below the pulley 16 on the shaft 15, is a pulley 21which is embraced by the belt 17. Carried by the lower end of the shaft20 is a beveled gear wheel 22.

Hangers 23 are secured to the frame 1 and to the lowermost cross tie 18,and, carried by the hangers are the bearings 24. Rotatably mounted inthe bearings 24 is a shaft 25 and carried by the shaft 25, in mesh withthe beveled gear wheel 22, is a beveled gear wheel 26. To the oppositeend of the shaft 25 is secured a pulley 27 which pulley is embraced by abelt 28 connecting with any suitable source of power (not shown).

A cylinder 29 is carried by the shaft 15, which cylinder is made up of aseries of sections 30, each of which sections are made up of a series ofintegral rings 31 uniformly spaced apart and of uniform thicknesses.Each of the sections is provided with internally projecting ribs 32, theforward faces 33 of which ribs are substantially on a radial line fromthe center of the cylinder and the rearmost face 34 of each rib iscurved. Each of the ribs is provided with an opening 35 extendingthroughout its length.

To position the sections of rings together I have provided the endplates 36, each of which plates is provided with a bearing 37 embracingthe shaft 15 and secured thereto.

A number of stay-rods 38 are carried by the plates 36 and extend througheach rib of each section of rings 31, the ends of the stayrods beingthreaded and provided with nuts 39 to clamp the sections between theplates 36.

Mounted in suitable bearings (not shown) positioned on the upper facesof the cross ties 18, are the shafts 40, and carried by the shafts are aseries of saw blades 41 and 42; the number of blades corresponds to thenumber of spaces between the rings 31. Carried by each shaft 40, at itslowermost end, is a gear wheel 43, which wheels mesh with a gear wheel44 carried by the shaft 20.

Positioned on the upper faces of the frame 1 is a pair of standards 45and supported by the standards 45 is an angular shaft 46. A number ofteeth 47 are carried by the shaft 46, the number of teeth correspondingto the number of spaces between the rings 31. Adjacent each end of theshaft 46 is a lever 48 and carried by the free end of the lever 48 is aweight 49. Carried by the machine frame 1 is a vertically disposeddividing board 50 interposed between the saw blades 41 and 42. Carriedby the machine frame, adjacent its upper end, is a hopper 51 and securedto the shaft 15 and operating in the hopper is a screw-conveyer 52. Theend of the hopper, adjacent the cylinder, is open and communicates withthe interior of the cylinder 29. Carried by the machine frame 1,adjacent the lower end of the cylinder 29,

is a receiving-chute 53 open-ended at its top and arranged to receivebolls from the cotton after they have passed through the cylinder.

The side faces of the rings 31, adjacent their outer ends, are taperedso as to prevent choking by cotton dragged by the saws from within thecylinder.

Carried by the shaft 20 is a rotating brush 54, the bristles of whichbrush are arranged to remove such cotton that might gather in the teethof the saw blades 41 and. 42.

In the practical operation of the machine, power is applied to thepulley 27 and all of the operating parts of the machine simultaneouslydriven. In this manner the cylinder is driven in the direction shown byarrows in Fig. 6, and, in the same figure direction-indicating arrowsillustrate the direction of travel of the saw blades 41 and 42 and thebrush 54.

After the machine is set in motion cotton within the bolls is fed to thehopper 51 and is moved through the hopper into the cyl inder 29 by theaction of the conveyer 52, and by reason of the inclination of thecylinder 29, the cotton and bolls are carried by gravity andsuccessively operated upon by the saw blades 41 and 42.

By reason of adjacent portions of the cylinder and saw blades 41 and 42rotating in the same direction, and by reason of the peculiarconstruction of the ribs 32, the cotton is separated from the bolls bythe teeth of the saws which engages and draws the cotton from its bolls,and, further by reason of the shape of the rear faces of the ribs 32clogging of the bolls within the pockets formed by the ribs isprevented; and by reason of the ribs traveling in the same direction asthe teeth of the saw blades the cotton and bolls not acted upon will becarried upwardly by the ribs and discharged again on to the saw blades.Such cotton as may be carried upwardly by the ribs and rings is clearedfrom the rings and ribs by the teeth 47. The loose cotton that clings tothe teeth of the saws and is not discharged therefrom is cleaned fromthe teeth of the saw blades by the action of the brush 54.

The partition board 50 serves to prevent the cotton which might becentrifugally thrown from the saw blades 41 from being thrown againstthe blades 42, and thus carried upwardly into the cylinder.

If desired it is obvious the feed may be varied, either by changing thespeed of rotation of the cylinder, or by varying the inclination of thecylinder by a manipulation of the jack 7. In this manner, and by reasonof the length of the cylinder and the number of saws operating betweenthe rings of the cylinder, all of the cotton is separated from the bollsand the cot-ton discharged into a suitable container located beneath themachine, and the bolls discharged from the cylinder into the chute atthe lower end of the cylinder.
